本节将介绍如何使用 Tailwind CSS 开发一个现代化的响应式企业官网，包括页面布局、组件开发、响应式设计等方面。

页面布局

导航栏组件

// components/Navbar.tsx
import { useState } from 'react';const Navbar = () => {const [isOpen, setIsOpen] = useState(false);return (<nav className="bg-white shadow-lg fixed w-full top-0 z-50"><div className="max-w-7xl mx-auto px-4 sm:px-6 lg:px-8"><div className="flex justify-between h-16">{/* Logo */}<div className="flex-shrink-0 flex items-center"><imgclassName="h-8 w-auto"src="/logo.svg"alt="Company Logo"/></div>{/* Desktop Menu */}<div className="hidden md:flex md:items-center md:space-x-8"><a href="#" className="text-gray-700 hover:text-gray-900 px-3 py-2 text-sm font-medium">首页</a><a href="#" className="text-gray-700 hover:text-gray-900 px-3 py-2 text-sm font-medium">产品</a><a href="#" className="text-gray-700 hover:text-gray-900 px-3 py-2 text-sm font-medium">解决方案</a><a href="#" className="text-gray-700 hover:text-gray-900 px-3 py-2 text-sm font-medium">关于我们</a><button className="ml-8 bg-blue-500 text-white px-4 py-2 rounded-lg text-sm font-medium hover:bg-blue-600 transition-colors">联系我们</button></div>{/* Mobile Menu Button */}<div className="md:hidden flex items-center"><buttononClick={() => setIsOpen(!isOpen)}className="inline-flex items-center justify-center p-2 rounded-md text-gray-400 hover:text-gray-500 hover:bg-gray-100"><svgclassName={`${isOpen ?

};

Hero 区域

// components/Hero.tsx
const Hero = () => {return (<div className="relative bg-white overflow-hidden"><div className="max-w-7xl mx-auto"><div className="relative z-10 pb-8 bg-white sm:pb-16 md:pb-20 lg:max-w-2xl lg:w-full lg:pb-28 xl:pb-32"><main className="mt-10 mx-auto max-w-7xl px-4 sm:mt-12 sm:px-6 md:mt-16 lg:mt-20 lg:px-8 xl:mt-28"><div className="sm:text-center lg:text-left"><h1 className="text-4xl tracking-tight font-extrabold text-gray-900 sm:text-5xl md:text-6xl"><span className="block">打造现代化的</span><span className="block text-blue-600">企业数字体验</span></h1><p className="mt-3 text-base text-gray-500 sm:mt-5 sm:text-lg sm:max-w-xl sm:mx-auto md:mt-5 md:text-xl lg:mx-0">我们提供全方位的数字化解决方案，帮助企业实现数字化转型，提升运营效率，创造更大的商业价值。</p><div className="mt-5 sm:mt-8 sm:flex sm:justify-center lg:justify-start"><div className="rounded-md shadow"><ahref="#"className="w-full flex items-center justify-center px-8 py-3 border border-transparent text-base font-medium rounded-md text-white bg-blue-600 hover:bg-blue-700 md:py-4 md:text-lg md:px-10">开始使用</a></div><div className="mt-3 sm:mt-0 sm:ml-3"><ahref="#"className="w-full flex items-center justify-center px-8 py-3 border border-transparent text-base font-medium rounded-md text-blue-700 bg-blue-100 hover:bg-blue-200 md:py-4 md:text-lg md:px-10">了解更多</a></div></div></div></main></div></div><div className="lg:absolute lg:inset-y-0 lg:right-0 lg:w-1/2"><imgclassName="h-56 w-full object-cover sm:h-72 md:h-96 lg:w-full lg:h-full"src="/hero-image.jpg"alt="Hero Image"/></div></div>);

功能组件

特性展示组件

// components/Features.tsx
const features = [{title: '快速部署',description: '提供一站式部署解决方案，快速上线您的业务系统。',icon: (<svg className="h-6 w-6" fill="none" viewBox="0 0 24 24" stroke="currentColor"><path strokeLinecap="round" strokeLinejoin="round" strokeWidth={2} d="M13 10V3L4 14h7v7l9-11h-7z" /></svg>),},{title: '安全可靠',description: '采用业界领先的安全防护措施，保障您的数据安全。',icon: (<svg className="h-6 w-6" fill="none" viewBox="0 0 24 24" stroke="currentColor"><path strokeLinecap="round" strokeLinejoin="round" strokeWidth={2} d="M12 15v2m-6 4h12a2 2 0 002-2v-6a2 2 0 00-2-2H6a2 2 0 00-2 2v6a2 2 0 002 2zm10-10V7a4 4 0 00-8 0v4h8z" /></svg>),},// ... 更多特性

};

客户案例组件

// components/Cases.tsx
const cases = [{title: '企业A的数字化转型',description: '帮助企业A实现了全面的数字化转型，提升了30%的运营效率。',image: '/case-1.jpg',},// ... 更多案例

};

响应式优化

媒体查询策略

// styles/breakpoints.ts
export const breakpoints = {sm: '640px',   // 小屏幕设备md: '768px',   // 平板设备lg: '1024px',  // 小型笔记本xl: '1280px',  // 大型笔记本'2xl': '1536px' // 桌面设备
};// 使用示例
<div className="gridgrid-cols-1gap-6sm:grid-cols-2lg:grid-cols-3xl:grid-cols-4
">{/* 内容 */}
</div>

图片响应式处理

// components/ResponsiveImage.tsx
interface ResponsiveImageProps {src: string;alt: string;className?: string;
}const ResponsiveImage: React.FC<ResponsiveImageProps> = ({src,alt,className = ''
}) => {return (<picture><sourcemedia="(min-width: 1024px)"srcSet={`${src}?w=1200`}/><sourcemedia="(min-width: 768px)"srcSet={`${src}?w=800`}/><imgsrc={`${src}?w=400`}alt={alt}className={`w-full h-auto ${className}`}loading="lazy"/></picture>);
};// 使用示例
<ResponsiveImagesrc="/hero-image.jpg"alt="Hero Image"className="rounded-lg shadow-lg"
/>

响应式导航

// hooks/useResponsiveNav.ts
import { useState, useEffect } from 'react';export const useResponsiveNav = () => {const [isMenuOpen, setIsMenuOpen] = useState(false);const [isMobile, setIsMobile] = useState(false);useEffect(() => {const checkWidth = () => {setIsMobile(window.innerWidth < 768);if (window.innerWidth >= 768) {setIsMenuOpen(false);}};window.addEventListener('resize', checkWidth);checkWidth();return () => window.removeEventListener('resize', checkWidth);}, []);return {isMenuOpen,setIsMenuOpen,isMobile};
};

性能优化

图片懒加载

// components/LazyImage.tsx
import { useEffect, useRef, useState } from 'react';interface LazyImageProps {src: string;alt: string;className?: string;placeholder?: string;
}const LazyImage: React.FC<LazyImageProps> = ({src,alt,className = '',placeholder = 'data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7'
}) => {const [isLoaded, setIsLoaded] = useState(false);const [imageSrc, setImageSrc] = useState(placeholder);const imageRef = useRef<HTMLImageElement>(null);useEffect(() => {const observer = new IntersectionObserver((entries) => {entries.forEach((entry) => {if (entry.isIntersecting) {setImageSrc(src);observer.unobserve(entry.target);}});},{rootMargin: '50px'});if (imageRef.current) {observer.observe(imageRef.current);}return () => {if (imageRef.current) {observer.unobserve(imageRef.current);}};}, [src]);return (<imgref={imageRef}src={imageSrc}alt={alt}className={`transition-opacity duration-300${isLoaded ? 'opacity-100' : 'opacity-0'}${className}`}onLoad={() => setIsLoaded(true)}/>);
};

组件优化

// components/OptimizedCarousel.tsx
import { memo } from 'react';interface CarouselProps {items: Array<{id: string;image: string;title: string;}>;
}const OptimizedCarousel = memo(({ items }: CarouselProps) => {return (<div className="relative overflow-hidden"><div className="flex snap-x snap-mandatory overflow-x-auto">{items.map((item) => (<divkey={item.id}className="snap-start flex-shrink-0 w-full md:w-1/2 lg:w-1/3"><LazyImagesrc={item.image}alt={item.title}className="w-full h-64 object-cover"/><h3 className="mt-2 text-lg font-medium text-gray-900">{item.title}</h3></div>))}</div></div>);
});OptimizedCarousel.displayName = 'OptimizedCarousel';

动画效果

滚动动画

// hooks/useScrollAnimation.ts
import { useEffect, useRef } from 'react';export const useScrollAnimation = (options = {}) => {const elementRef = useRef<HTMLElement>(null);useEffect(() => {const observer = new IntersectionObserver((entries) => {entries.forEach((entry) => {if (entry.isIntersecting) {entry.target.classList.add('animate-fade-in');observer.unobserve(entry.target);}});}, options);if (elementRef.current) {observer.observe(elementRef.current);}return () => {if (elementRef.current) {observer.unobserve(elementRef.current);}};}, []);return elementRef;
};// 使用示例
const Section = () => {const animationRef = useScrollAnimation({threshold: 0.1});return (<divref={animationRef}className="opacity-0 transition-opacity duration-1000">{/* 内容 */}</div>);
};
